Virtual reality (VR) functions as a substantial transformative tool which delivers therapeutic interventions particularly in exposure therapy. This paper investigates the implementation of metaverse-based virtual reality to create flight simulations for children with autism spectrum disorder (ASD) and social phobia. The proposed solution provides a personalized controlled space through which users can experience airplane boarding, in-flight interactions, and disembarkation with the support of VR tools. The system aims to expose users to these situations within a controlled space to minimize their stress levels before they face actual air travel. The system would adapt the environment to meet the specific needs of the user, thus offering an individualized therapeutic approach. This adaptation is performed with the aid of visual and audio feedback by incorporating verbal and a non-verbal user behavior determination models. The models would identify the user’s attitude through speech analysis, facial recognition, physiological reactivity identification, and gesture recognition. The system is a work-in-progress and is expected to offer a personalized and real-time adaptive approach once complete, making it more effective than other methods in the literature.
